Item Description

Completeness (as a percentage) of symmetry-unique anomalous difference data within the sphere defined by the diffraction limits (_reflns.d_resolution_high and _reflns.d_resolution_low) relative to all possible symmetry-unique anomalous difference data within that sphere. In the absence of an anisotropy description this is identical to _reflns.pdbx_percent_possible_anomalous.
